Review of polarized hadron beams

A review of facilities for acceleration of polarized hadron beams is given. First, medium energy beams accelerated in linacs or cyclotrons are overviewed, that is without noticeable depolarization problem, at PSI, TRIUMF and LANL. Beams accelerated in synchrotrons at LNS, BNL, KEK will be then examined in more details with emphasis on techniques used to reduce the effects of depolarizing resonances. Finally, the particular case of the FNAL high energy beam will be presented. Perspectives for future very high energy beams will be briefly outlined and recent experimental results from the first experimental test of the Siberian Snake concept at IUCF will be discussed.
